**Summary** Install new `@apply_metadata()` on PPTX, TSV, XLSX, and XML and remove decoration from PPT. **Additional Context** - Alphabetical order turns out to be hard, so this is the remaining "easy" delegating partitioner and the remaining principal partitioners. - Replace use of `@process_metadata()` and `@add_metadata_with_filetype()` decorators with `@apply_metadata()` on principal partitioners (those that do not delegate to other partitioners. - Remove all decorators from delegating partitioners (PPT in this case); this removes the "double-decorating".
